Coldheart

A shadowy presence in Marvel's Modern Age, Coldheart stepped onto the scene in 2006's New Avengers: Illuminati #1, brought to life by the acclaimed team of Brian Michael Bendis and Alex Maleev during one of Marvel's most seismic storytelling eras. With only a handful of catalog appearances, this is a rare, enigmatic figure whose footprint spans the landmark Civil War event and its chronicles — rarefied company for any character. Sharing pages with heavyweights like Iron Man, Mister Fantastic, and Namorita places Coldheart squarely at the heart of Marvel's most consequential conflicts of the mid-2000s, making every appearance a collector's find worth tracking down.
